Born in 1931 into an intellectual family, Dr. Penrose is a professor at the University of Oxford. He proved that if too much mass accumulated in too small a place, collapse into a black hole was inevitable. At the boundary of a black hole, called the event horizon, you would have to go faster than the speed of light — the acknowledged cosmic speed limit — to get away. He showed that the black hole would become a gateway to the end of time, the end of the universe. He is also famous for discovering Penrose tiles, a way of tiling an infinite floor without ever repeating the pattern.
